As expected, this was a fairly tedious experience but made bearable by having decent sanders to work with.
There is not a great deal to say about sanding, but here are some pics anyway.
This is the starboard cockpit deck and seatback, freshly sanded.
I snipped the support piece out of the rear cabin wall before sanding here, to add some excitement to the process.
I marked them with a bit of blue tape as it happened, so that I could easily find them to patch them later.
As here on the front cabin wall and Dorade boxes.
I will sand and feather-edge them at some point when the sanders are in action again. This is the cockpit, with its patches in place.
